[infinispan-issues] [JBoss JIRA] (ISPN-11341) Client requests go to wrong server with binary storage

Client requests go to wrong server with binary storage ------------------------------------------------------ Key: ISPN-11341 URL: https://issues.redhat.com/browse/ISPN-11341 Project: Infinispan Issue Type: Bug Components: Core, Hot Rod, Server Affects Versions: 9.4.18.Final, 10.1.2.Final, 11.0.0.Alpha1 Reporter: Dan Berindei Assignee: Gustavo Fernandes Priority: Major Fix For: 10.1.3.Final, 11.0.0.Alpha2, 9.4.19.Final Caches with BINARY storage accept {{byte[]}} keys, but add a prefix to indicate that the input was a {{byte[]}} and not a {{WrappedByteArray}}. This happens in {{BinaryEncoder.toStorage()}}, before the segment of the key is computed, so the segment computed by the server is different from the segment computed by the client (based on the key without the prefix). Since the client doesn't know (and shouldn't know) the server cache's storage type, the server should always compute the segment of the key based on the {{byte[]}} sent by the client. The simplest way to achieve that would be to make {{BinaryEncoder}} skip the marshalling for {{byte[]}}. The only problem is that we don't want users to put in a {{WrappedByteArray}} and get back a {{byte[]}}, so we should disallow {{WrappedByteArray}} keys and values in {{Cache}} methods.
